Our picks

Best for: Python devs building teams of role-based agents

Strength: Open-source framework under the MIT license with no usage caps; you pay only for LLM tokens and your own hosting.

Limitation: Code-first (Python); the managed AMP platform's free tier is just 50 workflow executions/month, and Enterprise is custom-priced.

Pricing (2026-10-16): Framework free (MIT); AMP Basic free (50 executions/mo); Enterprise custom.
